Abstract

1,086,853. Moulding hollow articles. B. A. Z. BRUUN. Sept. 28, 1964 [Sept. 26, 1963], No. 39436/64. Heading B5A. A hollow article is formed from a granular thermoplastic material, such as polythene, by filling the space between a mould 1 and a core 2 having downwardly divergent side walls with the material, forcing the material against the wall of the mould by applying pressure to the core and the material by a heavy block 3, heating the mould to fuse a layer of material thereagainst and finally cooling the mould and removing the excess material. The layer left in the mould may then be removed or may be further heated to smooth it. A lip may be formed on the article by pressing the upper edge of the layer left in the mould downwards with a suitably shaped member (see Fig. 5, not shown) and two articles formed by the above process may be pressed together whilst still in their moulds to fuse them and form an enclosed hollow article.
